Block-AP (EfficientQAT w/o E2E-AP)

EfficientQAT involves two consecutive training phases: Block-wise training of all parameters (Block-AP) and end-to-end training of quantization parameters (E2E-QP).

In this repo, we provide the quantized checkpoints of Block-AP. Anyone can use them to reproduce our results or carry following research.

Usage

Please refer https://github.com/OpenGVLab/EfficientQAT for details. These checkpoints can be used to following E2E-AP, as well as be inferenced directly.
